Basic Loop with [ str_replace]

hello-world · 09-05-2009, 01:37 PM

I have a problem with replacing and looping.I need your help please to change
This line

Quote:

The quick brown {fox} jumps over the lazy {dog}

To this

Quote:

The quick brown cat jumps over the lazy mouse.

PHP Code:


			
$string = 'The quick brown {fox} jumps over the lazy {dog}';
$arr = array("fox" =>"Cat","dog"=>"mouse");
preg_match_all("/{.*?}/",$testing,$matches);

By the way how to practice looping in php ?
Is there any good exercise for it ?

You don't necessarily need a loop to achieve this. You could do the following:

php Code:

$szItem   = 'The quick brown {fox} jumps over the lazy {dog}';
$aReplaceThese  = array('fox', 'dog');
$aReplaceWidth  = array('cat', 'mouse');

$szItem         = str_replace($aReplaceThese, $aReplaceWidth, $szItem);
echo $szItem;

Although, if you wish to practice loops, then I could show you how to achieve it with a foreach loop.

or you can also use the translate function:

php Code:

<?php
$string = 'The quick brown {fox} jumps over the lazy {dog}';
$arr = array("{fox}" => "cat","{dog}" => "mouse");
echo 'before: ' . $string . "\n";
$string = strtr($string, $arr);
echo 'after: ' . $string;
?>
